· CVS red copper check valve is a red copper tube full hermetic valve body structure with inside filter screen. For the sealing surface, it is PTFE sealing membrane design. The valve disc has guide device and restoring spring. A linear sealing is realized between the valve seat and the PTFE sealing membrane.

Application:

· CVS red copper check valve is used on the exhaust pipe of the compressor to prevent the condensed liquid refrigerant flowing back to the compressor.

Features:

· Brass valve seat, PTFE sealing membrane design on the sealing surface, inside filter screen so that the product has both filter and check valve functions.
· Almost zero leakage in the recerse operation.
· Red copper tube full hermetic valve body structure to ensure higher external sealing performance.
· Universal ODF port is convenient in replacement. ODF port size:1/4~3-1/8
· High flow rate and very low flow resistance.
· Straight-through type, compact and lightweight.
· With PTFE sealing membrane, it is applicable to all types of refrigerant. The applicable medium temperature:-40°C~+120°C

Technical Parameters:

· Applicable Refrigerant:HCFC , HFC;
· Applicable Medium Temperature:-40°C~+120°C;
· Maximum Working Pressure:Refer to the attached Specification sheet
